Unfortunately, we were unable to get in through the front door in the middle of the night. The front door has to be opened via an app, but it didn't work. Since it wasn't possible to contact Happy People Gaudi during the night, we had to wait outside the hotel for almost 2 hours until another guest randomly came down. There were a total of eight guests waiting. The next day, I contacted Happy People Gaudi by phone, as they didn't respond to emails. Here I received arrogant treatment and compensation, which was so minimal that it was almost insulting.
Also be aware that the hotel is very noisy.
